Movies too smooth on 4K LCD (not SOE)

I believe the C8 is a native 120hz panel. The 4K/60 spec is for displaying 60 frames per second. The TV will take that 4K/60 and simply copy those frames 1:1 to 120fps/hz.

But for movies, you are dealing with 4K/24fps/hz so it copies 5 times.

Theoretically, let's say they released the Hobbit in 48fps on UHD and you have a 120hz panel. 48x2 = 96 or 48x3 = 144. None of those numbers multiply to 120 so we need interpolation for the extra frames.

It's all about matching the native hz of the display panel. The panel is 120hz no matter what signal you are throwing at it in the end. It just copies those frames to get to 120hz.

This is how I understand the subject and if I'm wrong, someone please chime in.
